Limited flame spread materials and material assemblies are used in clothing in order to reduce the possibility of their burning and thereby itself constituting a fire hazard. These include clothing such as ladies' wear made of synthetic fibres and children wear of all kinds and also other protective clothing where protection against heat and fire mainly due to accidental contact with small igniting flames is required in circumstances where there is no significant heat and f~e hazard. The performance of such clothing is expressed in terms of a limited flame spread index. Following three indexes of performance have been covered: a) b) Index 1 -- Materials which do not spread flame but may form a hole on contact with a flame. Index 2 -- Materials and material assemblies do not spread flame and do not form a hole on contact with a flame. a hole on contact with a flame, They also give only limited after flame. It is not possible to specify a higher index for materials and material assemblies which do not give any after flame or damage at all, because classification has been found to be inconsistent due to slight inter laboratory variations. Index 1 materials are thermoplastics which do not spread flame, if accidentally contacted with a flame but do not protect the underlying material or skin. Index 1 materials should only be usedas a part of Index 2 or Index 3 material assembly and should not be worn next to the skin. Protective clothing may consist of several, separate dress materials or garments, or it may be a single dress material or garment with one or more layers. Normally it is sufficient for the outer material to have limited flame spread properties, and material assemblies ffom multi-layer clothing are tested by applying the flame to the outer surface. Optional alternative testing and marking requirements are given for material assemblies from dress materials or garments where there is a risk that inner layers might be exposed to flame contact (see 4.3,4.3.1.1 and 4.3.1.2). The limited flame spread properties of the textile materials and material assemblies are measured both before and after an appropriate cleansing or water soaking procedure and the procedure employed is indicated by a durability index. The composition of the Committee responsible for the formulation of this standard is given in Annex A. c) Index 3 -- Materials and material assemblies do not spread flame and do notfo~ For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2:1960 `Rules for rounding off numerical values (revised)'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. IS 15742:2007 Indian S~arzda~d TEXTILES -- REQUIREMENTS FOR CLOTHING MADE OF LIMITED FLAME SPREAD MATERIALS AND MATERIAL ASSEMBLIES AFFORDING PROTECTION AGAINST HEAT AND FLAME -- SPECIFICATION . 1 SCOPE 1.1 This standard specifies the performance requirements for the limited flame spread properties of textile materials and material assemblies used in protective clothing affording protection against heat and flame. 1,2 This standard is applicable to clothing such as ladies' wear made of synthetic fibres and children wear of all kinds and also other protective clothing where protection against heat and fue mainly due to accidental contact with small igniting flames is required in circumstances where there is no significant heat and fire hazard. 2 REFERENCES The following standards contain provision which, through reference in the text, constitute provisions of this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision and parties to agreement based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below: 3.1 Limited Flame Spread Index -- A number indicating that the material or material assembly achieved one of the levels given in 7. 3.2 Durability Index -- A letter X or R indicating that the material or material assembly was subjected to a cleansing procedure specified in 6 befor~ being tested for limited flame spread. 3.3 Textile Material -- A single fabric or other product, for example one layer of a woven, knitted, or coated fabric or a multi-layered fabric or other product combined prior to the garment manufacturing process, for example a laminated or quilted fabric.
